【Abstract】 This paper deals with some mechanical problems related to the regional ground stress field in analysis and calculation at Lu-bu-ge hydro-power station. 1.According to the principle of mathematical statistics and probability, cause of formation are carried out for the ground stress field. 2.The direction of regional tectonic strain field is computed by the finite element regression method. 3.Comparisions are made betweeen the calculated displacement results and the results of the in-situ displacement measurements of rock chamber model tests, further verified the reasonableness of the regression ground stress field.更多还原
